To all whmn it may concern.-

Be it known that I, JUsTUs A. TRAUT, a citizen of the UnitedStates,residing at New Britain, Hartford county, Connecticut, have 5 inventedcertain new and useful Improvements in Scrapers, of which the followingis a full, clear, and exact description.

My invention relates to improvements in scra ers.

T e object is to facilitate adjustment of the parts and improve theconstruction so that it may be adapted to use .under many differentcircumstances. I have sought to construct the parts so that they may bemanufactured readily and assembled or taken apart without diificulty.

The referred form of the invention is shown 1n the accompanying singlesheet of drawings, in which Figure 1 is a side view of the scraperembodying the improvements of my invention. Fig. 2 is a front view ofthe same. Fig. 3 isa rear view of the scraper with the handle shown insection. Fi 4 is a rear view of the back member of the head. Fi 5 is aside view of the same. Fig. 6 is a p ar. view of a fragment of thehandle.

The handle is preferably formed in two ortions-a grip member 1 and abody mem- The head of the scraper carries the blade 3 and is preferablyprovided with an auxiliary grip or handle 4.

5 and 6 are the frontand rear members,-

respeetively, of the head, between which the blade is clamped.

7 is a screw located between the upper and lower ends of the plates 5 6.This screw passes freely through plate 5 and takes into plate 6, so asto produce, in effect, a hinged joint which may be adjusted to and froto vary the widths of the space between plates 5 6. r

8 8 are screws arranged at opposite edges of the plate 6 andscrew-threaded therein. The ends of these screws project into cavitiesin the opposite face of the member 5, but are not screwthreaded therein.The

function of these screws is to preserve the alinement of plates 5 6 andto act as s acers to uaranteev the substantial parallellsm of sai plate,whereby the ready substitution of blades 3 is permitted. The screws 8 8alsoperform a stop function, the upper edge of the blade 3 taking abearing against said screws so thatv blade will be projected'uniformlyfrom the clamping-jaws. These stop-screws. '8 8, as we shall term them,may be shifted'up or down on late 6, there being a series of screw-holesa ong opposite edges thereof to permit this shifting of the screws to bemade. By this meanswhen blade 3 wears down or if a short blade-is to besubstituted the screws 8 8 may be moved to any one of the holes 8, 8 or8 so as to adapt the holder to the particular blade to be used.

9 is a main adjusting-screw having a stophead whereby it may beeasilyoperated. When approximate adjustment of the plates 5 6 has been securedby the adjustment of screws 7 and 8 and the blade inserted, the user mayset u on screw 9 in such a manner as to powerfu 1y clamp the blade 3.The rear of the back member 6 of the head is provided'with a pair oflugs 10 10, to which the handle is pivoted.

11 is a curved arm extending from the rear of the back member andprovided with a curved slot. This arm is preferably formed of a separatepiece of metaland riveted to the lug 12.

13 is a screw. preferably provided with an enlarged head for engagementb the thumb Patentedjan. 29, 1907.,
